Description

PROCESSING OF LOCATION-BASED INFORMATION

FIELD

[0001] The invention relates to a method for processing location- based information in a mobile terminal, to a mobile terminal, and to a computer program product that encodes a computer process for processing location- based information in the mobile terminal.

BACKGROUND

[0002] The supply of commercial and general-purpose services can be extended to comprise location-based services, i.e. services dependent on the location of the user, by using wireless data transmission technology. Ex- amples of such services are location-based news and weather services, event advertisements, tourist guides, timetable services, shop and restaurant adver- tisements, map and positioning services, and search and entertainment ser- vices.

[0003] According to the prior art, location-based information is transmitted either as SMS (Short Message System) messages or by using push technology as service messages to a terminal. A great deal of location- based messages may be received, and the user has to read each message separately, accept the storage of each message, or delete the message. This causes extra and unnecessary trouble to the user, especially if s/he is not in- terested in every type of location-based information. The user also needs to delete old messages stored earlier. The information in the stored messages may also be outdated before the user has time to utilize it.

BRIEF DESCRIPTION

[0004] It is an object of the invention to provide an improved method for processing location-based information in a mobile terminal, an improved mobile terminal, and an improved computer program product for encoding a computer process for processing location-based information in the mobile ter- minal.

[0005] As one aspect of the invention, a method for processing lo- cation-based information in a mobile terminal is presented, the method com- prising: receiving at the mobile terminal location-based information related to the location of the terminal and transmitted wirelessly using push technology.

The method also comprises: displaying the location-based information to the user dynamically using a specific menu-type user interface component de- signed for displaying location-based information, in which user interface com- ponent the location-based information is divided into categories by subject.

[0006] As one aspect of the invention, a mobile terminal is pre- sented, comprising a receiver that is configured to receive location-based in- formation related to the location of the terminal and transmitted wirelessly us- ing push technology. The mobile terminal also comprises a processing unit that is configured to display the location-based information to the user dynamically using a specific menu-type user interface component designed for displaying location-based information, in which user interface component the location- based information is divided into categories by subject.

[0007] As one aspect of the invention, a mobile terminal is pre- sented, comprising means for receiving location-based information related to the location of the terminal and transmitted wirelessly using push technology.

The mobile terminal also comprises means for displaying the location-based information to the user dynamically using a specific menu-type user interface component designed for displaying location-based information, in which user interface component the location-based information is divided into categories by subject.

[0008] As one aspect of the invention, a computer program product is presented that encodes a computer process for processing location-based information in a mobile terminal, the computer process comprising: receiving location-based information related to the location of the terminal and transmit- ted wirelessly using push technology. The computer process also comprises: displaying the location-based information to the user dynamically using a spe- cific menu-type user interface component designed for displaying location- based information, in which user interface component the location-based in- formation is divided into categories by subject.

[0009] The invention provides several advantages. Because the re- ceived location-based messages are automatically transferred to the dynamic user interface component, the actions of the user are not needed to individually process each message. This makes the reception of location-based service messages considerably user-friendlier; any location-based information interest- ing to the user is constantly available in the user interface component, whereas the user need not even notice any information that is unimportant to him or her — even though it, too, was available in the user interface component. The user interface component operates dynamically, which means that new messages can be transferred to the user interface component for the user to access, the information in the user interface component can be updated, if the information content changes, and outdated information can be deleted from the user inter- face component. This way, uptodate location-based information is constantly available to the user.

DESCRIPTION OF EMBODIMENTS

[0011] Figure 2 shows one embodiment of the structure of a mobile terminal 104 configured to receive location-based information. In addition, it shows an embodiment of a transmitter system 102 providing location-based information and connected to the terminal 104. The terminal 104 can be a de- vice suited for data transmission anywhere, such as a subscriber terminal of a mobile system, a portable computer equipped with a telecommunications con- nection, a PDA (Personal Digital Assistant) device, or any other corresponding transceiver unit. The terminal 104 can also be a receiver unit specifically de- signed for processing location-based information.

[0012] The connection between the terminal 104 and transmitter system 102 can be implemented using wireless data transmission technology.

Wireless data transmission technology refers herein to any system that en- ables wireless data transmission to mobile terminals within the service area of the system. The system may be GSM (Global System for Mobile Communica- tions), GPRS (General Packet Radio Service), UMTS (Universal Mobile Tele-

communications System), or any other corresponding mobile system, a system employing the Bluetooth® or IrDA (Infrared Data Association) data transmis- sion technology, or a WLAN (Wireless Local Area Network) system. The area within which location-based information is transmitted can be determined by defining the location coordinates within which the information is transmitted, or by restricting the number or service area of transmitter units transmitting loca- tion-based information. In the first case, the movement of users can be moni- tored using an appropriate positioning method, and when the user is within the service area, location-based information is transmitted to his or her terminal.

The positioning system can for instance be a GPS (Global Positioning System) system, an E-OTD (Enhanced Observed Time Difference) system or a corre- sponding positioning system based on triangulation, or — if a more approximate positioning is sufficient — a transmitter unit is determined, in the service area of which the terminal moves.

[0013] Let us next examine the structure of the mobile terminal 104 with reference to Figure 2. The terminal 104 of Figure 2 comprises an antenna 206 and a receiver 208 that can be a prior-art radio receiver and operate in a

Bluetooth® data transmission system, for instance. In addition, the terminal 104 comprises a processing unit 210 that controls and monitors the functions of the terminal 104, such as the processing of a received radio signal and the management of the components of the user interface 212. The processing unit 210 also controls the reception of location-based information and the dynamic processing thereof in the terminal 104.

[0014] The dynamic processing of location-based information com- prises identifying a received message as a location-based message, storing the message in the terminal, modifying the location-based information, if the sender of the location-based information changes the content of the location- based information, and deleting outdated location-based information from the terminal.

[0015] The processing unit 210 can process the location-based in- formation under the control of a message processing application implemented by software and installed in the terminal 104. The processing unit 210 is today generally implemented as a digital signal processor (DSP) that contains any software necessary to control the terminal 104, but various hardware solutions — such as ASIC (Application-Specific Integrated Circuit) — are also possible.

[0016] The terminal 104 can also comprise a positioning system 218 or the terminal 104 can be connected to an external positioning system.

The positioning system can be used when checking whether the terminal 104 is in an area in which location-based information is transmitted. The terminal 5 104 also typically comprises a voltage source 216, which can be a chargeable battery, for example. The terminal 104 also comprises a user interface 212 comprising a display, a management unit — such as a keyboard or touch screen — and an operating system. The user interface 212 also comprises a user interface component 214 designed to display location-based information.

The user interface component 214 can be a menu-type solution as shown in

Figure 4, in which the location-based information is divided into categories by subject, on the basis of which the user finds the desired location-based infor- mation. The user interface component 214 can also be a separate software application which when executed displays the available location-based infor- mation to the user. The software application can be an additional component to the message processing application or a software application separate from the message processing application.

[0017] Figure 3 shows an example of the software layers of the mo- bile terminal 104. The hardware and the software 300 controlling the hardware - especially the processing unit 210 — constitute the lowest layer. The operat- ing system 302 controls the initiation and execution of the software in the ter- minal 104 and thus acts as an interface between the hardware and software.

The operating system can for instance be Symbian OS used generally in mo- bile stations. The software in the terminal 104 comprises the user interface 212. One component of the user interface 212 is the dynamic user interface component 214 designed for displaying location-based information.

[0018] The above thus describes the mobile terminal 104 having a data transmission connection to a transmitter system 102 transmitting location- based information. The transmitter system may comprise a server unit 200, transmitter unit 202, and antenna 204. The server unit 200 defines the content of the location-based information to be transmitied and the area in which the location-based information is transmitted. Even though in Figure 2, the server unit 200 is only connected to one transmitter unit 202, it can also be connected to several transmitter units, thus offering location-based information in a wider area. The transmitter system 102 can thus be a radio data transmission sys-

tem or a part thereof or a single transmitter unit that transmits location-based information within its own service area.

[0019] Figure 1 shows an embodiment of the invention. The mobile terminal 104 arrives at the service area 100 of the transmitter unit 102 trans- mitting location-based information, in this case at a railway station. When arriv- ing at the service area 100, the terminal 104 starts to receive location-based information related to the service area 100 as service messages 106 transmit- ted using push technology. Controlled by the message processing application, the terminal 104 identifies the received message as location-based information and stores the information in the message in the terminal 104. Controlled by the message processing application, the terminal also updates the content of the user interface component 214 containing location-based information so that the received location-based information becomes available to the user. A notification on the new content in the user interface component 214 containing location-based information is forwarded to the user of the terminal 104. The user can be notified using an icon on the display of the terminal 104, an audio or vibration signal or some other known indication method.

[0020] When arriving at a railway station, the user of the terminal 104 may need information on train timetables, and opens from the user inter- face component 214 containing location-based information the category con- taining local information to find information related to the railway station, such as timetables. The timetable information may have been transmitted to the terminal 104, in which case it can be read directly from the user interface com- ponent 214, or only information on where to find timetable information may have been transmitted to the terminal 104. In the latter case, the URL (Uniform

Resource Locator) address of an Internet web page may have been transmit- ted to the terminal, and if the user so desires, the terminal 104 can open the web page. It is also possible that information on where the timetables of the railway station are located is transmitted to the terminal. The message can be similar to 108, for instance.

[0021] When the terminal 104 exits the service area 100 of the transmitter unit 102 transmitting location-based information, the terminal, con- trolled by the message processing application, deletes the outdated informa- tion from the user interface component 214 containing location-based informa- tion. The cutdated information can also be left in the user interface component 214 for the user or it can be deleted in accordance with a criterion defined by the user, after a specific time, for instance. A message similar to 110 can also be left in the user interface component 214 for a specific time.

[0022] The following describes a method for processing location- based information in a mobile terminal with reference to Figure 5. The execu- tion of the method is started in step 500, after which step 502 is executed, i.e. a transmitter unit transmitting location-based information transmits location- based messages in its service area by using push technology.

[0023] Next, step 504 is executed, in which the routine checks whether the mobile terminal is receiving location-based messages. This com- prises checking the location of the terminal and the configuration of the termi- nal. The location of the terminal can be determined for instance by using a po- sitioning system integrated to the terminal or a positioning system connected to the terminal. Positioning can also be left out, in which case location-based messages can be received within the service area of the transmitter system 156 providing location-based information. By positioning, it is thus possible to de- fine more accurately the area in which location-based information is transmit- ted. Checking the configuration of the terminal comprises for instance checking whether the terminal is configured to receive location-based messages. The terminal may be configured to receive all location-based message, only certain types of location-based messages or not to receive any location-based mes- sages. The configuration of the terminal may be managed by the user.

[0024] If the terminal fulfils the criteria, the terminal receives a loca- tion-based message in step 506 which comprises identifying the received message as a location-based message and storing the message in the termi- nal. In the terminal, the processing of the message can be controlled by a message processing application implemented by software. After this, step 508 is executed, in which the received location-based information is displayed to the user in a specific user interface component designed to display location- based information. The user interface component can be a menu-type solution as shown in Figure 4, or a separate software application operating either as an additional component to the message processing application or as a software application separate from the message processing application. A change in the content of the user interface component containing location-based information is notified to the user in step 510 which is executed when new information is available to the user in the user interface component. The notification can be the display of a certain icon on the display of the terminal, an audio or vibration signal, or some other indication provided by a generally known signalling method.

[0025] Next, in step 512, the routine checks whether the content of the location-based information transmitted by the service provider has changed. Part of the information content may still remain unchanged. The changed information can be distinguished from the new information for in- stance by means of an identifier in the transmitted message. The information stored earlier in the terminal and the changed information have the same iden- tifier, whereas the identifier of completely new location-based information can- not be found in the stored information. If it is detected that the content of the stored location-based information has changed, step 514 is executed, i.e. the content of the user interface component containing location-based information is updated. After this, the change in the location-based information can be noti- fied to the user by using one of the above-mentioned signalling methods.

[0026] If the terminal exits the area in which the service provider transmits location-based information as a result of step 516, the location-based information related to the area is deleted from the user interface component in step 518. The exiting of the terminal from the area can be detected based on the use of a positioning system, or the terminal detects that the location-based information related to the area is no longer available from the transmitter unit.

Step 518 is also executed when the transmitter unit stops transmitting location- based information, even though the terminal still is in the service area of the transmitter unit. The execution of the method is stopped in step 520.

[0027] In addition to the above-mentioned message processing methods, location-based information can also be processed according to spe- cific criteria in the terminal. The criteria may comprise for instance limitations in the reception of location-based information, the presentation format of location- based information in the dynamic user interface component, and the deletion of location-based information after a given time. The criteria can be defined by theuser.

[0028] The method can be used in a terminal of the type described above. The method can also be implemented by a computer program product that encodes a process for the processing of location-based information in a mobile terminal, the computer process comprising the actions of the method described above. The computer program product can be stored on a computer program distribution medium. The terminal can read the computer program distribution medium. The distribution medium can be any known medium used for distributing a computer program from the manufacturer/vendor to the end user. The distribution medium can for instance be a medium readable by the terminal, a program storage medium or storage medium, a memory readable by the terminal, or a software distribution package, and a signal that the termi- nal can read, a telecommunications signal or a compressed software package.

[0029] Even though the invention is above described with reference to the example of the attached drawings, it is clear that the invention is not re- stricted to it but can be modified in many ways within the scope of the attached claims.
